CONVEYER DoG.

Application filed January :41,1912?.- seri/neng. 164,915.

This invention relates generally to conveyor dogs and consists of certain novel fea tures of construction, combinations and arrangements of parts as will be hereinafter more fully described and particularly pointed out in the appended claim.

ln the accompanying drawing: Fi, 'e 1 is a fragmentary side elevation of a conveyor with a dog embodying my invention applied thereto. Y

T*"igrue 2 is a top plan view of the dog.

Tigure 3 is a detail elevation of the rocker. figure 4 is a top plan view of the rocker. Figure 5 is a detail elevation of the bracket. 1"igure G is a top plan view of the bracket. "igure 7 is an end view of the bracket. ligure 8 is a detail view of the pivotpin.

ln the past, conveyers have been provided at space/.l peints longitudinally thereof with upstanding pins or projections for maintainarticles of various kinds in proper spaced relation upon such conveyers while being moved thereby. For instance-in cert-ainV vehicle body manufacturing plants or factories, conveyers for vehicle bodies have been provided with such pins for maintaining the body carrying trucks in the desired position upon the conveyers while in transit. However with such constructions, the trucks had to be lifted up over the pins to mount the trucks upon or remove them from, or to advance them or move them back upon the conveyers. In practice such adjustment of the trucks relative to the conveyors consumed considerable time and labor and therefore has proven very objectionable. A'

lith the present invention the conveyer is s provided with self actingdogs or stopsthat permit the trucks to be mounted upon or ad- 1fanced upon such conveyers without the necessity of lifting the trucks as previously described.

Referring now lo the drawing, 1 is a. section of a conveyer. and 2 is a dog embodying my invention carried thereby. As shown, the dog comprises only three parts, namely, a bracket y 3, a rocker 4, and a pivotl pin 5. Preferably the bracket 3 has a substantially flat base V6 that is secured by suitable headed elements such as the bolts 7 to the conveyer 1, and is provided intermediate of its ends with an upstanding bifureated lug 8 for su orting the pivot pin 5 and rocker 4. InBtrhe present instance the pin 5 extends through the furcation 9.to the furcation 10 and has a .reduced portion l1 that extends through the f urcation 10, while the. rocker 4 is located-,between the furcations .(1y 'and 10 and is provided intermediate of its ends with a transversely eX- tending bore 13 that receives the pin 5. With this construction the portion 14 of the rocker vin rear of the pivot is solid and is preferably provided at its rear end with an elongated solid proj ection l5 that extends longitudinally ofthe said rear end and is normally rei ceived inan opening 1 6 of somewhat similar shape in the base 6 of the bracket. If desired, the opening 16 and the projection 15 may be so proportioned, one to the other that the rear end ofthe projection 15 will abut the rear yend ofthe openingl when the rocker is in normal operative position as shown in Figure 1. As a result the strains and stresses imparted by the body supporting truck to the rocker may be taken up by the base 6 through engagement of the projection 15,V

therewith and Will'thereby relieve the pivot pin 13 of such stresess. The portion 17 of the rocker in advance of the pivot 13 is recessed as shown at 18 for lightness, hence the rocker .is weighted at its rear end and will normally assume the position shown in` Figure l.

yTo expedite the attachment of the bracket 3 to the eonveyer 1, the forward edges ofthe fur'cations 9 and 10 ofthe lug are recessed as shown at 19 and 2O respectively. Thus, the bolt 7 or other suitable securing element may be readily inserted in the forward opening 22 Yin the base for engagement with the convcyer V1. Moreover these recesses 19 and 20 are so arranged that the furcations may be used directly as stops when for instance the frames of the body supporting trucks or other carriers are lower than usual. In this connection it will be noted that the for Yard lower edge of the rocker is. also recessed as shown at 24 corresponding to the recesses 19 and 20. hence the frames of such carriers may engage the furcations 9 and 10 without effecting the rocker 4. The upper and lower edges 25 and 26 respectively of the portion 17 of the rocker are preferably parallel, while the extreme forward end of said portion 17 is bevelled rdownwardly as shown at 27 so that the proper engagement between the carrier and rocker vmay be readily obtained.

' Thus,vfrom the foregoingdescription, itk

Construction and can be mimuifaietured et a comparatively low Cost. Such dogs may he easily and qiiiclly secured to a suitable conveyer and when so applied Will function itutomatically for accomplishing the results de- Sired.

While its is believed that from the foie going description, the nature und advent-ege of my invention will he readily aplimrent, l desire to have it understood that l do not limit myself to Whatis herein shown :ind deserihed and that such changes may he resorted to when desired es fell within 'the scope of what is claimed.

YVhut l claim as my invention:

ln a Conveyor attachment, a hase having an upstending ear, and a dog pivoted intermediete the ende Vthereof to the ear and having it rear portion reduced to deiine a shoulder engaging the 1oase to limit pivotal movement el the dog, said base being; provided with e slet receiving the reduced portion of said dog, one Well o .Said slot being en gagged by Jthe opposed edge oli' seid reduced portion to receive the thrust on the dog.

testimony whereof l ellix my signature.
